- Please show the work to understand the process. AI generated steps have been wrong.I need the answer as soon as possible. A helical compression spring is to be made of oil-tempered wire of 4 mm diameter with a spring index of C=10. The spring is to operate inside a hole, so buckling is not a problem, and the ends can be left plain. The free length of the spring should be 80 mm. A force of 50 N should deflect the spring 15 mm. (Take: G= 77 GPa) 1- Determine the minimum hole diameter for the spring to operate in. 2-Determine the solid length. 3-Determine a static factor of safety based on the yielding of the spring if it is compressed to its solid length.

A helical compression spring is fabricated from ASTM A229 oil-tempered wire (Figure 1) and has the mean coil diameter D = 10 mm, wire diameter d = 0.9 mm, total number of active coils Na = 14.5, and the modulus of rigidity G = 79 GPa. Find: a. The torsional yield strength of the wire. b. The static load corresponding to the yield strength and spring constant. c. The solid and free heights and the pitch of the body coil of the spring. d. Whether buckling will be possible, if the ends are squared-ground.
